fn empty() -> TraitFlags
rustc_private)Returns an empty set of flags.
fn all() -> TraitFlags
rustc_private)Returns the set containing all flags.
fn bits(&self) -> u32
rustc_private)Returns the raw value of the flags currently stored.
fn from_bits(bits: u32) -> Option<TraitFlags>
rustc_private)Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: u32) -> TraitFlags
rustc_private)Convert from underlying bit representation, dropping any bits that do not correspond to flags.
fn is_empty(&self) -> bool
rustc_private)Returns true if no flags are currently stored.
fn is_all(&self) -> bool
rustc_private)Returns true if all flags are currently set.
fn intersects(&self, other: TraitFlags) -> bool
rustc_private)Returns true if there are flags common to both self and other.
fn contains(&self, other: TraitFlags) -> bool
rustc_private)Returns true all of the flags in other are contained within self.
fn insert(&mut self, other: TraitFlags)
rustc_private)Inserts the specified flags in-place.
fn remove(&mut self, other: TraitFlags)
rustc_private)Removes the specified flags in-place.
fn toggle(&mut self, other: TraitFlags)
rustc_private)Toggles the specified flags in-place.
